Wed Mar 16 2016: SModelS v1.0.4 is now available for download:


If you use SModelS, please cite the quick guide (arXiv:1412.1745), the original SModelS paper (arXiv:1312.4175) as well as the tools used by the code: Pythia6.4, NLL-fast and PySLHA. For convenience a .bib file is provided with the code containing all relevant references. Likewise, a .bib file is provided in the database folder with references to all the ATLAS and CMS analyses used.


SModelS is based on a general procedure to decompose Beyond the Standard Model (BSM) collider signatures presenting a Z2 symmetry into Simplified Model Spectrum (SMS) topologies. Our method provides a way to cast BSM predictions for the LHC in a model independent framework, which can be directly confronted with the relevant experimental constraints. Our concrete implementation currently focusses on supersymmetry searches with missing energy, for which a large variety of SMS results from ATLAS and CMS are available. The main ingredients are
